Yes, you should be concerned but since it is too late... don't lose any sleep over it. It is impossible to know if CT was applied to your bag, which would most likely affect your film. There have been enough self-reports by folks who put film in checked luggage with no detrimental effect to convice me that the newer two-phase screening equipment is reducing the probability of problems... but only processing the film provides evidence of YOUR film getting CT or no CT exposure. If all your film got was x-ray, there is little to worry about. Since it is too late, though... don't lose any sleep over it.

Agreed. I am just annoyed at myself that I didn't think fast enough. The machine was just a big stainless box, that I fed my luggage through before I cleared customs (they made us put all our bags through, including carry ons). I now need to decide if I keep using the film (I have 4 exposed rolls, 10 un-exposed). I might get a C-41 roll developed in Penang when we get there in 2 days.
